| + | Step by step: Recompiling the Ubuntu stock kernel natively (for example to patch it) coming from a stock Ubuntu 12.04 install. | ||
| + | As of writing the kernel-version is **3.0.27** and will have to be replaced when another kernel comes out/is used. The created files will be copied to a safe place (/ | ||

| + | Become root for all steps | ||
| + | < | ||
| + | Install dependencies for the kernel and build it: | ||
| + | < | ||
| + | apt-get build-dep linux-ac100 | ||
| + | apt-get install build-essential lzop | ||
| + | cd /usr/src/ | ||
| + | apt-get source linux-ac100 | ||

| + | < | ||
| + | Apply patches if wanted. In this example I use gordans overclocking patches from [[http:// | ||
| + | < | ||
| + | patch -p1 < tegra_1200.patch</ | ||
| + | (Note that one patch didn't apply cleanly, but the errors were pretty obvious and easy to fix manually.) | ||

| + | ===== 3.10.x Kernel series ===== | ||
| + | 3.10 build process is close to 3.0 for-next. | ||
| + | Device-tree is mandatory, you need to build it and concatenate with a kernel: | ||
| + | < | ||
| + | make dtbs | ||
| + | cat arch/ | ||
| + | </ | ||
| + | But 3.10 don't use paz00_defconfig anymore. Instead is uses tegra_defconfig (main idea of device-tree is to have all-in-one kernel and choose drivers on boot time using device-tree): | ||
| + | < | ||
| + | ===== Mainline Git Kernel ===== | ||
| + | From 3.15, AC100 finally boots the official mainline kernel ! | ||
